Technical Field

The invention belongs to the technical field of food processing, and particularly relates to a red date processing technology.

Background

The red dates are 'medicinally edible', and are used as food and medicinal; it has nutritive value, and can prevent and treat diseases, strengthen body constitution, and prolong life.

The red date is prepared from the processing science of the traditional Chinese medicine, so the red date is a special diet with both medicinal efficacy and food delicacy.

The traditional red date processing technology generally adopts water boiling, chilling, air drying and then smoking, and the prior art has the following defects that the active ingredients for the red date traditional Chinese medicine are lost due to water boiling, the smoking causes air pollution, the smoking seriously affects the product quality and the like. Meanwhile, improper smoking temperature control easily causes deterioration of red date components. The red dates processed by the traditional processing technology have low medicinal value.

Disclosure of Invention

In order to solve the problems in the prior art and further optimize the prior art, the invention provides a red date processing technology to realize the following purposes: (1) the problems of nutrient loss and component deterioration in the red date processing process are solved; (2) improving the medicinal value of the refined red dates. (3) Is convenient for realizing the large-scale batch production of the red dates.

In order to solve the technical problems, the invention adopts the following technical scheme:

a red date processing technology comprises the following steps:

step 1, red date selection

The Xinjiang dried red dates with thick meat, solid quality, heavy weight and bright color are selected by adopting a red date screening machine.

The Xinjiang dried red dates are jun dates or gray dates.

The adopted jun dates have the length of 3.5-4.5cm and the diameter of 2-2.7 cm;

the adopted fructus Choerospondiatis has a length of 2.3-3.3 cm and a diameter of 1-1.5 cm.

Step 2, soaking

Soaking the red dates after grading and selection in 0.5-1.5% sodium hydroxide solution for 10-30 min; the soaking temperature is room temperature. The percentage is mass percentage.

Step 3, cleaning

Cleaning fructus Jujubae under high pressure to remove impurities, and drying and sterilizing with high energy particle-molecule breaking dynamic sterilization treatment equipment. The water content of the red date pulp is controlled to be 15-30% of the weight of the red date.

The high-pressure ultrasonic cleaning comprises the following steps: the red dates are washed by an ultrasonic bubbling washing machine, a brush fruit washing machine and an air-drying draining machine in sequence, and the washing water pressure is 0.1-0.2 MPa. Cleaning time: washing for 1-3 times from feeding to discharging for 5-20 min.

The high-energy particle-molecule impact section dynamic sterilization equipment comprises: the model of the device is XYC-DT-12 HP.

And (3) drying and sterilizing: placing the red dates on a drying rack, pushing the drying rack into a drying device for drying treatment, wherein the drying temperature is 50-80 ℃, the drying time is 4-8 hours, and the water content of red date pulp is controlled to be 15-30% of the weight of the red dates.

Step 4, removing kernels

Taking out the red date kernel by a full-automatic kernel removing and opening machine, opening the pulp for later addition of ingredients.

The length of the pulp opening is the same as that of the red dates.

Step 5, steaming, drying and processing

And (4) putting the red date pulp subjected to denucleation treatment into a steaming vehicle, and pushing the steaming vehicle into a dry steaming device for water-proof dry steaming. Steaming with 105-140 deg.C high temperature steam for 10-100 min, taking out, placing in a shady place, and sun drying for 1-5 hr.

The water separation dry steaming: placing fructus Jujubae on tray with sieve holes, and evaporating to dryness with water vapor.

And putting the dried red date pulp into a steaming vehicle, pushing the red date pulp into a dry steaming device for secondary steaming, and performing dry steaming at the high temperature of 105-140 ℃ for 10-60 minutes in a water-proof way, taking out the red date pulp, and drying the red date pulp in the shade for 1-5 hours in a dark place.

Drying again, steaming for the third time, and steaming at 105-140 deg.C for 1-30 min in water-proof manner.

Step 6, adding ingredients

Adding ingredients into the steamed red date meat from the opening to prepare a semi-finished product.

The ingredients are any one or combination of more of walnut kernels, cashews, almonds, raisins, hawthorn cakes and cranberries;

the dosage of the ingredients accounts for 10-50% of the weight of the red dates.

Step 7, post-treatment

The red dates added with ingredients enter a microwave dryer along with a chain plate machine, wherein the transmission speed of the chain plate machine is 0.1-1.5m/min, the microwave blowing speed is 3-10m/s, the microwave drying time is 60-120min, the microwave frequency is 2450 +/-30 HZ, and the microwave power is 40-80 Kw. The water content of fructus Jujubae is 10-20% of the weight of fructus Jujubae.

And packaging the post-processed semi-finished product by using a full-automatic packaging machine to prepare a finished product.

By adopting the technical scheme, the invention has the beneficial effects that:

(1) by adopting the red date processing method, the loss of nutrient elements of the red dates caused by water boiling or soaking can be effectively avoided; meanwhile, the problems of environmental pollution, red date scorching and the like caused by smoking are effectively avoided.

(2) By adopting the red date processing method, the nutritional ingredients such as protein, fat, sugar, vitamins, calcium, iron and the like in the red dates can be effectively protected, the medicinal value of the red dates on lung cancer, cardia cancer, hematemesis and the like is protected, the effects of tonifying middle-jiao and Qi, nourishing stomach and strengthening spleen, nourishing blood and strengthening spirit, moistening heart and lung, regulating yingfen and weifen, promoting the secretion of body fluid, nourishing the color, dredging nine orifices, assisting twelve meridians, clearing away the toxicity of drugs and the like are further highlighted, and the medicinal value is high.

(3) The red dates processed by the method are nutritious and delicious, and simultaneously, the red dates can nourish bodies and condition qi and blood.

(4) The red dates processed by the method are convenient to realize large-scale processing of the red dates, the production efficiency is improved, and the production cost is reduced.
